Abstract: PROBLEM TO BE SOLVED: To provide an information processing system and an arbitration method capable of arbitration with high accuracy.SOLUTION: An initiator IP 1-1 successively generates a plurality of access requests according to data transfer necessary for certain processing, to issue them to a target IP 5. A calculation device 2-1 calculates a first transfer rate from a total data amount of data transfer and a preset transfer allowable time. For each of predetermined set timing, the calculation device 2-1 calculates a second transfer rate from a data amount already transferred to the initiator IP 1-1 and a time elapsing after the start of the data transfer from the initiator IP 1-1. Based on the comparison result between the first transfer rate and the second transfer rate, the calculation device 2-1 sets each weight which the initiator IP 1-1 gives to correspond to each access request before the issue. An arbitration circuit 4 performs arbitration of transfer processing, based on the weight made to correspond to the access request.
